3 SHEETS-SHEET 3- n'r STATES PATENT GEORGE N. TAYLOR, OF EAST PROVIDENCE, RHODE ISLAND, ASSIGIN'OR TO. UNIVERSAL WITIDING COMPANY, OF BOSTON, MASSACHUSETTS, A. CORPORATION OF MASSACHU- WINDING-MACHINE.

To all whom it may concern:

Be it known that I, GEORGE N. TAYLOR, a citizen of the United States, residing at East Providence, in the county of Providence, State of Rhode Island, have invented certain new and useful Improvements in Winding- Machines, of which the following 1s a specification.

My invention relates to improvements in winding machines and" particularly to conewinders for producing conical packages of thread, yarn or other textiles. The object of my invention is to provide a machine for winding a cone-package of improved'form, having a convex base and a concave, apex end, whereby the yarn or other material is so disposed about its central core or support as to secure a more stable structure and a free and unrestricted delivery thereof in unwinding the cone. To this end my improvement consists essentially in providing means for positively and progressively displacing the cone-holder in an axial direction in relation to the traverse of the thread-guide which deposits the coils of winding thereon, so that successive layers of the winding are gradually stepped forward away from the large end of the cone to cause the base to assume a convex shape while the apex end becomes correspondingly concaved.

The manner and means for carrying out the improvement are fully described in the following specification, illustrated by the accompanying drawings, in which like reference characters designate like parts. In the drawings Figure 1 is a front elevation of a well known type of winding machine showing my improvement applied thereto;

Fig. 3, an enlarged, detail view of the cone-holder shifting-means, showing its connection with the main elements of the machine; and

Figs. 4 and 5, enlarged, detailed views of various operating parts of the shiftingmechanism. v

Referring first to Fig. 1, A designates the main frame of the winding machine in which are rotatably mounted the horizontal winding-spindle B and cam-shaft G. On the v Specification of Letters Patent. P t t Man-o 2, 19% Application filed August 9, 1916. Serial No. 114,005.

rearward end of the spindle B is a drivingpulley D adapted to be rotatively connected therewith by suitable clutch-devices, not herein shown or described in detail, and through which the machine'is operated from a driving-belt connected to any suitable source of power. Outwardly beyond the driving-pulley D is a belt-pulley E fixedly secured to the shaft or spindle B and connected by a belt e to a lower pulley E. The pulley E is fixed on the end of a countershaft J which carries a pinion at its opposite end meshing with a gear 0 on the end of the cam-shaft C. The shaft J is journaled in a bearing in a casing J' which serves as a gear-box and oil-reservoir for the gears y, a.

Fixedly mounted on the shaft C within the sides of the frame A is the traversecam O, of cylindrical construction formed with a helical groove 0 on its periphery. Engaging the groove 0 of the cam C is a roll or stud is depending from the under side of a slide or crosshead K to connect the latter to be reciprocated from the cam. The orosshead K is mounted to slide in a slot in the horizontal cross-piece f of a traverseframe F which is constructed with two upright arms f, f pivotally mounted on the cam-shaft C, in: accordance with a type of construction generally employed in the present style of machine. The traverse-frame F also comprises an outer, overhanging portion F formed with a groove or track 7, see Fig; 2, in which a traverse-bar or rod K 7 slides. The'inner end of the traverse-bar K is connected with the reciprocable crosshead or slide K, and at its outer end is carried an upright arm or thread-guide G provided with the usual guiding-slot or notch 9.

Attached to or formed as a part of the overhanging portion F of the frame F is a plate or back F against which the guide Gr bears to direct its path of travel in relation to the winding-spindle B. As shown more particularly in Fig. 2 the guiding-face f of the traverse-frame back F is inclined to the axis of the spindle B to adapt the guide to travel in a plane parallel with the conical surface of the cone-tube holder H which rotates with the spindle. Depending from the outer arm f of the traverse-frame on which the yarn is being deposited -Usually a dogging-mechanism is employed for controlling the swinging movement of the frame F to prevent the guide Gr from vibrating or following an irregular course as it travels across the surface of the winding. As shown in Fig. 2 the present doggang-device consists of a curved sector or track M fastened to the frame A concentric with the axis of the traverse-frame F and provided with a tapered groove m, see Fig. 1, with which a frictionshoe or arm m on the frame F engages. As the dogging-device is not essential to the present invention,

, however, and since its construction and method of operation are well known in the art, it is not'herein shown or described in detail. Suffice it to state that the dog-sector or track M is'hung on a stud or screw m projecting from the side of the frame A and this stud forms a convenient support for attaching certain parts of the cone-shifting devices of the present improvement as later more fully described.

Toprovide for the longitudinal shifting of the cone with respect to the traverse of the thread-guide during the winding l have preferred to arrange for a sliding movement of the cone-holder H on the winding-spindle B with which it rotates. Referring particularly to Fig. 3, the cone-holder H is of. conventional construction and as here shown has a hearing it on the overhanging portion of the spindle B and a second bearing h on the outer, reduced end thereof. The outer surface of the holder H is tapered to receive the paper tube or shell X, on which the cone is wound, and usually means are provided for securing the tube in place thereon. A

common expedient is to employ expanding dogs or arms having teeth adapted to engage the interior of the cone-tube, and arranged for withdrawal therefrom to release the tube to allow for removal of the completed packages. As this detail of the machine forms no part of the present invention, it is not herein shown or described; but it might be mentioned that the tube-securing means is operated through a relative movement between the cone-holder H and a coaxial sleeve N also mounted on the spindle-B at the base endof the holder. As shown in Fig. 3 the sleeve N is keyed rotati'vely to the spindle B. by means of the spline awhile being adapted to slide longitudinally thereon.

The sleeve N is connected rotatively with raaaeaa is formed with an annular groove or slot a to adapt it to be moved on the shaft or spindle B by means of a rockable lever L en'gaging therewith, and through the connection of the sleeve with the cone-holder the latter is displaced longitudinally of the spindle as more fully explained hereinafter. From the above it will be understood that the sleeve N serves as the means for operating the cone.-

holder H to efiect its shifting movement and for the present purpose the sleeve might be constructed as an integral part of the holder,

if desired.

Referring particularly to Fig. 2, the cone-, holder operating-lever L is pivoted on a stud Z secured in an arm 0 fastened. to the front ofthe main frame A of the machine. As before indicated the arm or bracket 0 is mounted on the outer end of the stud m which secures the trave'rse-frame dog-sector or track M in place, and a set-screw 0' holds it in osition thereon. At its lower end the arm is held by a screw 0 fastened in the frame A and is formed with an'upwardlyprojecting lug 0 Extending through the lug 0 is a screw 0 secured therein by a check-nut 0 to allow for adjustment thereof. The end of the screw 0 is adapted to con tact with the side of the arm f of the traverse-frame F to serve as an adjustable stop therefor as the thread-guide Gr swings toward the cone-holder. It is usual to provide a stop of this nature for the traverseframe F and the screw 0 here shown is the same as generally used as a holding-means therefor. It will therefore be observed that the arm 0 may be applied to machines of the type herein illustrated which are already provided between the lever and the sleeve which allows the latterto rotate freely with the spindle B while being slid thereon. Se-

cured in the lower end ofthe lever L is a screw Z on which is rotatably mounted a be traversed along .ing the lever spherically-shaped roll Z. The roll Z engages the sides of an inclined slot p in a cam-plate P fastened to the front of the arm f of the traverse-frame F. As shown in the detail view, Fi 4:, the cam-plate P is preferably formed of sheet-metal and constructed with a flange go, through which it is Zastened to the frame F by means of the screws 1), see Fig. 2. The angular slot {9 is formed in a rearwardly-extending tai piece p of the plate P and is inclined outwardly away from the side of the frame F with a straight portion 12* at itsend. The ball-like roll Z rides between the sides of the slot p while being maintained in engagement therewith without play during the rocking of the lever L, due to its spherical shape. As the traverse-frame F swings outwardly in the direction indicated by the arrow 2, Fig. 2, during the building of the cone, the cam-plate P acts to rock the lower end of the lever L away from the side of the frame A or in the direction indicated by the arrow 3, Fig. 1. The straight portion 19 of the slot 12 is designed to allow the frame F to be moved outwardly a slight distance beyond the position which it assumes upon the completion of the cone without operatthe thread-guide G away from contact with the surface of the cone to allow for removing the latter from its holder H after it has been completed, and prevents unnecessary shiftin of the cone-holder during this operation. he method of operation of the complete device is as follows:

In preparing the machine for operation the cone-tube or'shell X is slipped over the outside of the holder H and secured in place thereon through the operation of any suitable fastening-devices as usually provided. The thread or yarn y is then led up from its source of supply through the slot 9 in the guide G and its end fastened to the tube X or holder H. The operator next swings the traverse-frame F back into operative position with the guide G bearing on the surface of the tube X and the machine is then ready for winding the cone. When the frame F is carried, back to its initial position, as illustrated in Fig. 2, the coneholder H will be shifted to the left, as viewed in Fig. 1, to the limit of its travel in this direction. Now, as the' power is applied to the machine to rotate the spindle B and reciprocate the thread-guide G, at the commencement of the winding the yarn will the holder H between the points 02-00., Fig. 1. As the yarn builds up on the tube X it forces the thread-guide G away from the axis of the spindle B, thereby causing the traverse-frame F to swing outwardly in the direction indicated by the arrow 2, Fig. 2. This swinging movement of the frame F acts through its cam- L. This provides for moving plate P to raduall rock the lower end of the lever away rom the frame A, or to the left as viewed in Fig. 1, and the upper end of the lever L will therefore be swung 1n the opposite direction or to the right. As the upper, end of the lever L is swung to the right it acts through its roll Z engaging the sleeve N to shift the cone-holder H in the same direction. In this manner as the winding progresses the cone-holder H is gradually shifted along the spindle B to displace it longitudinall with respect to the fixed path of traverse o the guide G. This causes the guide to deposit the yarn in stepped back layers, progressively receding from the larger end of the tube X and appreaching theopposite, smaller end, so that the mass gradually assumes a convex contour at the base of the cone and a shelved, concave formation at its apex. Fig. 1 illustrates the cone-holder H at its extreme, outward position in relation to the frame A of the machine at the start of the winding with only a few layers of yarn y deposited on the tube X; while Fig. 3 shows the coneholder at its extreme, inner position with the shape of the completed cone represented by the dot-and-dash lines Y.

It will be understood that the object of giving this concavo-convex form to the opposite ends of the cone is to provide a more stable structure of its mass, while also facilitating the delivery of the yarn in unwinding it therefrom. The convexing of the base of the cone produces a structure better able to resist rough treatment in handling and packing, while also provided for setting the cone on its base without damaging or deranging the ends of the layers thereof. The overlapping or stepping forward of the ends of the layers at the base gives a stancher structure, while the cupshaped form at the opposite end of the cane also tends to protect the layers and add to the general stability of the whole. The most important feature of improvement, however, resides in the fact that the coils of winding are prevented from overrunning or becoming displaced across the edge of the cone at its base. That is to say, the coils will be prevented from slipping down over the edge of the cone or becoming pulled over in loose lengths across its base. Such overruns or loose ends interfere with the delivery of the yarn when it is drawn off over the small end of the cone and frequently cause straining or breaking of the strands before the end can be freed.

I am aware that it is not broadly new in the art to produce a cone-package with the layers disposed to form a convexed base and a concaved apex end. Heretofore, however, this method of winding the cone has only been applied to machines of the drum, or friction-drive type. The present machine is distinguished from winders of the latter type in that the cone or package is rotated positively by a winding-spindle whereas 1n the drumor friction-winder the cone is driven through frictional contact of its sur ing to a regular system. In other words,

the coils are wound open and in a haphazard manner and a regular and systematic disposition of the windings is not attainable; In contradistinction to the drum method of winding, the machine of the present invention operates with a constant and uniform synchrony between the windingspindle and thread-guide to produce a package having a regular, systematic and precise disposition of the coils or turns of the winding and is hence known as a positive or precision winder. As is well lmown, the positive type of machine is far superior to that of the frictionor drum-drive style as regards the value of its product. Drumwound cones are badly formed, soft and irregular, with loose coils, overruns, cobwebs and other defects, while positive-wound packages are uniformly true and regular in shape, contain a maximum amount of material, with the windings so disposed as to provide for free and unrestricted delivery of the yarn under an even tension. It has been a simple matter to adapt a drum-winder towind the preferred form of cone herein described, only requiring that the drunrbe shifted along the drivlng-drum or roll to displace it with respect to the traverse of the thread-guide during the winding. In the present instance, however, with a machine arranged for. a positive drive of the cone, various problems are met with which have herein been solved in a simple and ingenious manner. 'llhe displacing of the cone with respect to the traverse is accomplished with out disturbing thev synchronous operation between the cone and the thread-guide, and

without disorganizing or rearranging theessential mechanism of the machine. Furthermore, the shifting of the cone is made consequent to a normal functioning of the general elements of the winding-mechanism and very fewnew elements are employed for the new operation required. The added parts are of simple construction, economical to manufacture and the complete device is adapted for attachment to standard types of machines without necessitating machine operations thereon or requiring material refitting thereof.
